Android API31+下EncoderProfiles.getAll无法解析问题求助

1. 修正API级别注解 #

EncoderProfiles.getAll()是**API 33（Android 13，对应Build.VERSION_CODES.TIRAMISU）**才新增的方法，你当前用的@RequiresApi(Build.VERSION_CODES.S)对应API31，注解级别不匹配，会导致IDE无法识别方法，同时低版本设备调用会崩溃。需将注解修改为：

@RequiresApi(Build.VERSION_CODES.TIRAMISU)

2. 确保项目与SDK同步 #

即便你已设置compileSdk=34，仍需确认：

• 本地已下载API34及对应版本的SDK Platform
• 执行File -> Sync Project with Gradle Files同步项目，让IDE加载新增的API方法
• 若同步后仍无效果，尝试清理缓存：Build -> Clean Project -> Build -> Rebuild Project

3. 兼容多版本的代码逻辑 #

由于CamcorderProfile仅在API33及以上被标记为弃用，可通过版本分支处理，同时保留对低版本设备的支持：

import android.media.CamcorderProfile
import android.media.EncoderProfiles
import android.hardware.camera2.CameraCharacteristics
import android.hardware.camera2.CameraManager
import android.os.Build
import androidx.annotation.RequiresApi
import android.util.Log

fun getAvailableEncoderProfiles(cameraManager: CameraManager, cameraId: String): List<Int> {
    val characteristics = cameraManager.getCameraCharacteristics(cameraId)
    val cameraDirection = characteristics.get(CameraCharacteristics.LENS_FACING)

    if (cameraDirection == CameraCharacteristics.LENS_FACING_FRONT) {
        return listOf(CamcorderProfile.QUALITY_HIGH).also {
            Log.d("CameraApp", "Front-facing camera detected, using QUALITY_HIGH")
        }
    }

    val qualities = listOf(
        CamcorderProfile.QUALITY_8KUHD,
        CamcorderProfile.QUALITY_4KDCI,
        CamcorderProfile.QUALITY_2160P,
        CamcorderProfile.QUALITY_1080P,
        CamcorderProfile.QUALITY_2K,
        CamcorderProfile.QUALITY_720P,
        CamcorderProfile.QUALITY_480P,
        CamcorderProfile.QUALITY_CIF,
        CamcorderProfile.QUALITY_QVGA,
        CamcorderProfile.QUALITY_QCIF,
        CamcorderProfile.QUALITY_LOW,
        CamcorderProfile.QUALITY_HIGH,
    )

    val availableQualities = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
        qualities.filter { quality ->
            try {
                EncoderProfiles.getAll(cameraId, quality) != null
            } catch (e: IllegalArgumentException) {
                false
            }
        }
    } else {
        qualities.filter { quality ->
            CamcorderProfile.hasProfile(cameraId.toInt(), quality)
        }
    }

    availableQualities.forEach { quality ->
        Log.d("CameraApp", "Available quality: $quality")
    }

    return availableQualities
}

4. 额外注意事项 #

• 部分QUALITY常量（如QUALITY_8KUHD）可能受硬件限制，无法被所有设备支持，捕获IllegalArgumentException的处理方式是合理的
• 若你的minSdk为26，版本判断可确保低版本设备正常运行
